- the shim 258 may be provided in a width w sufficient to maintain uniform compression of the composite (e.g., 60- 100% of the composite width).
- the base member 253a may encapsulate a plurality of narrower shims 258- la, 258-2a spaced apart and arranged to similarly limit and maintain uniform compression of the composite 250a.
- Figure 3 illustrates another exemplary structural bonding composite 350 including a multi-layered compressible (e.g., viscoelastic) base member 353, including first and second base layers 353-1, 353-2 and a rigid plate, shim or other such reinforcement member 358 sandwiched between the base layers 353-1, 353-2 and extending along a length of the bonding composite 350.
- the shim 358 may be provided in a substantially or relatively incompressible material, such as, for example, EPDM, Silicone, PVC, or aluminum.
- the shim 358 may be provided with a thickness t s (e.g., 20-30% of the composite thickness t, or about 0.03-0.09 for a composite having a thickness compression limit of 1 ⁇ 4 inch) selected to effectively limit the compressed thickness of the bonding composite 350, for example, to a predetermined allowable compressed thickness t ' (e.g., corresponding to an industry specified face clearance, such as, for example, 1 ⁇ 4 inch).
- the shim 358 may, but need not, be provided in a width substantially equal to the width of the base layers 353-1, 353-2 sufficient to maintain uniform compression of the composite (e.g., 80-120% of the composite width).
- Adhesive surfaces 354-1, 354-2, 355-1, 355-2 for bonding the composite to the frame member and fenestration unit, and for bonding the base layers 353-1, 353-2 to the shim 358, may be defined by the base layer material, or may be defined by adhesive layers or coatings applied to the sides of the base layers.
- the adhesive layers or coatings applied to the sides of a base layer of a structural bonding composite include one or more silicones.
- Silicones are synthetic polymeric materials that possess an extraordinarily wide range of physical properties. They can be low- or high-viscosity liquids, solid resins, or vulcanizable gums. They display an unusual combination of organic and inorganic chemical properties that are due to their unique molecular structure of alternating silicon and oxygen atoms shown below:
- the silicone adhesive curing reaction will result in development of a "crosslinked" elastomer from relatively low molecular weight viscoelastic polymers by means of a chemical reaction that forms these crosslinks and effectively extends chain length after contact to the frame member material resulting in a superior bonding tensile strength.
- curing silicones There are many types of curing silicones. Such systems may include (i) addition- cured, e.g., hydrosilylation cured (alternatively spelled "hydrosilation") silicones, (ii) radiation cure silicone, and/or (iii) condensation-cured silicones.
- Addition-cured silicones do not produce byproducts during curing.
- An adhesive based on this cure system is of higher quality and more dimensionally stable, and are a more preferred cure system.
- the addition cured composition typically contains: (1) a polymer which contains two or more vinyl functional groups; (2) a "hydrosilane” crosslinker component containing two or more SiH bonds; and (3) a precious metal catalyst such as a platinum catalyst.
- An exemplary addition-cured silicone is formed by reacting (1) a multiply-vinyl-containing organopolysiloxane with (2) an organopolysiloxane containing a multiplicity of SiH bond per molecule. This reaction is typically facilitated by the presence of (3) a platinum catalyst of the Karstedt type.
- Radiation cure silicones do not produce by-products during curing.
- An adhesive based on this cure system is of higher quality and more dimensionally stable, and are a more preferred cure system.
- the radiation-cured composition typically includes (1) silicone compounds exhibiting acrylic or epoxy functionality, or both, (2) a catalytic amount of a photoinitiator comprising an onium salt cationic photoinitiator or a silicone-soluble free-radical
- photoinitiator or a mixture thereof, and (3) additives such as reactive diluents, tackifiers for superior bonding tensile strength.
- Condensation-cured silicone adhesives cure a by-product such as water or alcohol while under-going the crosslinking reaction. Condensation cure is preferred as a secondary cure for the adhesive for superior bonding tensile strength.
- the base member 353a may include three (or more) base layers 353-la, 353-2a, 353-3a, with a rigid plate or shim 358-la, 358-2a bonded between adjacent base layers (e.g., by adhesive layers, not shown) to similarly limit and maintain uniform compression of the composite 350a.
- At least one reinforcement member may be bonded or otherwise attached to a lateral edge portion of the composite's base member. Any suitable bonding or attachment may be utilized, including, for example, at least one of acrylic and silicone.
- Figure 4 illustrates an exemplary structural bonding composite 450 including a compressible (e.g., viscoelastic) base member 453 having adhesive side surfaces 454, 455 (either defined by the base member or by adhesive layers/coatings, as described above) defining a non-compressed thickness t and bonded along a first lateral edge 456 to a relatively rigid (or of limited compressibility) spacer or other such reinforcement member 458 extending along a length of the bonding composite 450.
- a compressible (e.g., viscoelastic) base member 453 having adhesive side surfaces 454, 455 (either defined by the base member or by adhesive layers/coatings, as described above) defining a non-compressed thickness t and bonded along a first lateral edge 456 to a relatively rigid (or
- the reinforcement member 458 may be provided in a substantially or relatively incompressible material, such as, for example, a rubber, thermal plastic, or metal material.
- the member 458 may be provided in a material (or coated with a material) selected to prevent damage to the bonded surfaces.
- the reinforcement member 458 may be provided with a thickness ts selected to effectively limit the compressed thickness of the bonding composite 450, for example, to a predetermined allowable compressed thickness t ' (e.g., corresponding to an industry specified face clearance, such as, for example, 1 ⁇ 4 inch).
- reinforcement members 458-la, 458-2a may be bonded or otherwise attached to both lateral edges 456-la, 456-2a of the base member 453a to similarly limit and maintain uniform compression of the composite 450a.
- the laterally bonded reinforcement member 458 of Figure 4 may take a variety of forms.
- a sufficiently rigid gasket i.e., of limited compressibility
- that provides a seal between the fenestration unit and the inner stop of the frame member e.g., similar to the gasket 144 ' of Figure IB
- Figure 5 illustrates an exemplary structural bonding composite 550 including a compressible (e.g., viscoelastic) base member 553 having adhesive side surfaces 554, 555 (either defined by the base member or by adhesive layers/coatings, as described above) and bonded along a first lateral edge 556 to a relatively rigid (or of limited
- gasket 558 e.g., a preset dense gasket extending along a length of the bonding composite 550.
- the gasket 558 may be provided in any suitable material, such as, for example, rubber, elastomer, or thermal plastic. As shown, the gasket 558 may include a ridge, dart, flange, or other such interlocking portion 557 for interlocking engagement with an exterior stop of a frame member (as shown in Figure 1).
- the gasket 558 may be provided with a thickness t g selected to effectively limit the compressed thickness of the bonding composite 550, for example, to a predetermined allowable thickness (e.g., corresponding to an industry specified face clearance, such as, for example, 1 ⁇ 4 inch).
- a structural bonding composite may utilize both an internal shim (or other such reinforcement member) and a laterally attached reinforcement member, for example, to provide additional reinforcement against compression of the composite's base member.
